Submission. The Contractor will begin development of a construction schedule at the Award of Contract starting with the preliminary schedule and continue throughout the construction contract with the submission of a baseline schedule and monthly updates. This manual covers the construction scheduling portion from the initial design until the completion of construction.
B.I Construction Schedules
Generally, on projects with an estimated construction cost of less than $5 million, a computer generated Critical Path Method (CPM) Progress Schedule shall be submitted on Primavera SureTrak software or other approved software that is compatible with Primavera P3e software. However, Primavera Project Planner P3 3.0 or approved equivalent software shall be utilized on projects that meet one of the following criteria:
- New Construction or Reconstruction/Rehabilitation projects that require staging plans or a specific sequence of construction
- Major utility relocations.
- Significant right-of-way impacts.
- Estimated duration of longer than one construction season.
- All projects over $5 million construction cost
The specific software to be utilized on a particular project will be determined by Construction as part of the Final Scope Development process.
B.II Equivalent Software
Reference is made to Primavera products throughout this manual and also in the Specifications. It is understood that computer software technology is constantly changing and improving and as per Subsection 106.12 that Substitutes or "Or Equal" products are or may become available. To be approved as a Substitute or "Or Equal" the software must be completely compatible with the database that contains the Capital Program Management's design process schedule and budget as well as the construction scheduling from initial design through construction. The software shall be compatible with the hierarchy of the coding and able to import and export data within the NJDOT Capital Program Management's database without distortion of any coding or relationships contained in the database.
The Designer shall only utilize equivalent or compatible software, which has received written approval from the Department prior to their submittal of their technical proposal. The software utilized for the initial schedule shall not vary throughout the remainder of the design process.
The Contractor shall only utilize equivalent or compatible software for a project, which has received written approval from the Department. Forty State Business Days will be required for review and approval or rejection of the software. In order to obtain approval of a Substitutes or "Or Equal" product, the manufacturer of the software must demonstrate its compatibility by submitting all required documentation, demonstration disks, or other necessary information to the Bureau of Quality Management Services. The approved software utilized will not vary throughout the construction phase.
C. Best Practices
In developing a schedule, three basic items make CPM scheduling work:
- Clearly defined activities.
- Realistic duration’s.
- Good logic.
Other Practices Include:
- Negative lags will not be permitted.
- Do not use a Finish to Start relationship with a lag. An activity must be added to represent the lag time.
- A project shall have one beginning and one end. All activities shall have a predecessor and successor except the project’s start and finish milestones. No "Open Ends" will be permitted.
- Durations of work activities shall not exceed the update cycle. The Department requires the update cycle to be prepared monthly.
- "Suspension of Dates" will not be permitted. An activity must be added.
- If an activity has a Start-to-Start relationship - it shall be closed with a Finish-to- Finish or Finish-to-Start relationship. (No open ends)
- The completion date of the CPM schedule shall be the completion date in Subsection 108.10 of the project's Special Provisions, which shall be input as a Finish Milestone with a Late Finish Constraint. All intermediate milestones (Interim Completion Dates) required in the Contract shall be shown in proper logical sequence and input as either the “Start-no-Earlier-Than” or “Finish-no-Later-Than” date. Mandatory Finish and Mandatory Starts shall not be used.
- When updating, all "Out of Sequence" activities shall be corrected to reflect the current construction operations.
- Original durations shall not be changed from the approved Baseline Schedule.
D. Standard Coding
As a means of monitoring progress schedules, the Department has developed with the Consultant and Construction industries common coding structure and procedures to be utilized from design through construction. A Designer or Contractor shall utilize the Primavera template project containing the latest standard coding provided from the Department’s web site or will be sent upon request.
